Despite, being declared Ebola free in January, WHO warned of possible flare-ups in West Africa. Liberia, Sierra Leone and Guinea were the hardest hit nations.

“This latest case marks Liberia’s third flare-up of Ebola virus disease since its original outbreak was declared over on 9 May 2015.

The last flare-up in the country began in November 2015 and ended 14 January 2016,” WHO said in a “statement”

The virus which spreads by contact with infected blood and bodily fluids, has killed at least 11,300 people in West Africa since 2013.

The new flare-up comes days after WHO downgraded the health risk of the Ebola virus after nearly two years of a global emergency.

“Ebola transmission in West Africa no longer constitutes an extraordinary event, that the risk of international spread is now low, and that countries currently have the capacity to respond rapidly to new virus emergences,” WHO said.

Guinea is currently having a flare-up of the Ebola virus with new clusters of cases which continue to occur due to reintroductions of virus.

Following the flare up, Liberia closed its border with Guinea as a precautionary measure against the latest outbreak. However, WHO recently advised Liberia not to restrict travel and trade with its neighbouring countries.
